Claims.

My invention particularly concerns so-called gummed tape, that is, a paper strip one face of which is coated with a water soluble glue; or similar adhesive; this gummed tape being in gen- 5 'eral use for binding up parcels.

This gummed tape is supplied to the trade in helically wound coils of various widths and diameters and the outer end of the tape is-stuck on the coil body so that it will not unwind dur- When so fastened in place, the tape end is pulled loose again with great, diificulty; and not infrequently the tape ing it loose, is torn off, and when that occurs it is necessary to use a knife or similar-implement and cut thru the outer plies of the coil to free the tape end, which procedure entails the waste of a considerable length of the tape and loss of time.

In fastening the tape end to the coil body, the method of applying the moisture to only a small area of the adhesive surface of the tape end has been tried in order to limit the adhesion.

But thismethod is not practical, because of the difliculty of controlling the amount of moisture applied to the gummed surface of the tape. And even when only a relatively small surface of the tape end in this way is stuck to the coil it is still diiiicult to pull it loose without tearing the tape due to the strong adhesive quality of the gummed side of the tape. 1

, The object of my invention is to avoid such trouble and, by providing means for detachably securing the tape end in place, to facilitate the detaching of the tape end from the coil body so that the tape end may be readily pulledoff from the coil body without danger of tearing of the tape end.

40 I attain the object of my invention by interposing between tape end and coil body a transverse strip one face of .which is attached to the coil body and the other face of which is attached to the tape end, which strip is adapted to be pulled apart between its faces; or by limiting the adhesion of the tape end to the coil body to noncontinuous or' interrupted areas; in other words, causing the tape end to be fastened to the coil body only at isolated, small sized spots, or areas,

from which the tape end'may be easily pulled loose serially, progressively; that is to say, from one spot or area at a time, and thus be readily detached from the coil body.

The various means by which my invention may be carried into practice are more conveniently described with reference to the accompanying drawing.

In the drawing, Fig. 1 shows a perspective elevation of a coil of gummed tape with the tape end not yet stuck down on the coil body, and '5 this figure illustrates one means for carryingmy invention into practice; I

Fig. 2 is a view similar to Fig. l, but illustrates another means for carrying my invention into practice; 10

Fig. 3 illustrates one type of binder strip which may be interposed between the coil body and loose tape end for securing the latter in place in accordance with my invention;

Fig. 4. illustrates what takes place when the 15 tape end, after being fastened down by the means illustratedby Fig. 1, is forcibly torn loose; and

Fig. 5 illustrates still another means by which my invention can be carried into practice.

Referring to Fig.1, a. represents a coil of 20 gummed tape, and b illustrates its loose end. On the periphery e of the coil body, some distance from the extremity b' of the tape end, so as to leave a loose end which may be seized, is placed, transversely, a narrow strip c of paper, 25 which may be punched with a series of relatively large sized holes as d, see Figs. 1 and 3. This strip c contains adhesive material on its under side by which it is stuck to the coil. The function of these holes in the strip 0 is to limit the 30 direct adhesion between the gummed face of the tape end b and the periphery e of the coil body to relatively small, isolated, that is, nonadiacent, areas exposed by said holes. Thus, there is no continuous adhesion between the tape end and 35 the coil body, but, since on the contrary, such adhesion is discontinuous and interrupted, the tape end may be readily pulled loose. The. binder strip 0 is made of paper of loose texture so that -weakening and tearing of the tape end when pulling it loose from the coil body.

As illustrated by the drawing, the binder strip 45 c is placed some distance from the extremity b of the tape end b, so as to leave a projecting loose strip which may be readily seized when the tape end is to be pulled loose. Y

The binder strip 0 may be provided with one 50 adhesive face so that it may be readily stuck down transversely on the periphery of the coil body. But I also have found it practical to provide both faces of the binder strip with adhesive; their some convenient mechanical means may be onc ployed for moistening both faces of the binder strip, and the latter interposed between the coil body and tape end for securing the tape end in place with a minimum effort.

The binder strip illustrated by Figs. 1, and 3 may also be made of a wax, or oiled paper, or

similar moisture resisting material, provided with holes as d of ample size in the areas of which alone adhesion between the gummed face of the tape end and coiled body can take place.

In Fig. 2 I have illustrated a possible modification in the construction of my binder strip. In this case a binder strip c is provided with an adhesive coating on one face, so that it may be fastened on the periphery e of the coil body a. This binder strip, instead of having holes punched in it is imprinted with moisture resistant pigment or wax in the spots indicated by the circles 1, leaving free the relatively small areas 0 to which moisture can be applied for sticking down the tape end b2. The adhesion between the tape end and the coil body is thus again limited to isolated,

relatively small areas 9 from which the tape end I)! may be readily pulled loose.

Another means by which my invention may be carried into practice is illustrated by Fig. 5. In this case the peripheral face of the coil body a2 may have imprinted thereon, with, a moisture resisting pigment, a ribbon-like strip as :i, leaving uncovered adhesive portions k to which moisture may be applied for fastening the tape end m in place. Or, the arrangement of the binder strip :i may be reversed by making the moisture resisting imprinting only on the spots k, and leaving the surrounding surfaces free for the adhesion of the tape end to the coil body. But I deem the first described method and means for securing the tape end on the coil body (as shown in Figs. 1 and the most practical and convenient.

I claim:

1. In combination with a roll of gummed tape, meansfor detachably securing the free end of the tape in place, such means comprising a narrow strip of fabric interposed between said free end of the tape and the body of the roll; one face of said strip being provided with adhesive for fastening said face in its entirety on the body of the roll.

2. In combination with a roll of gummed tape, means for detachably securing the free end of the tape in place, such means comprising a narrow strip of fabric interposed between said free end of the tape and the body of the roll; one face of said strip being provided with adhesive for fastening said face in its entirety on the body of the roll, said strip composed of a web of relatively weak texture so as to be readily torn apart between its faces.

3. In combination with a roll of gummed tape,

'means for detachably securing the free end of the tape in place, such means comprising a narrow, perforated strip of fabric interposed between said free end of the tape and the body of the roll; one face of said strip being provided with adhesive for fastening said face in it s entirety on the body of the roll, said strip composed of a web of relatively weak texture so as to be readily torn apart between its faces.

4. In combination with a roll of gummed tape means for detachably securing the free end of the tape in place, such means comprising a narrow. perforated strip of adhesion resisting fabric interposed between said free end of the tape and the body of the roll; the perforations permitting the gummed face of the tape end to be attached to the body of said roll thru said perforations, and the latter limiting the adhesion between the tape end and the body of the roll to the areas of such perforations.

5. In combination with a roll of gummed tape, means for detachably securing the free end of the tape in place, such means comprising a narrow strip of fabric interposed between said free end of the tape and the body of the roll; one face of said strip being provided with adhesive for fastening said face in its entirety on the body of the roll, the other face of said strip provided with adhesion resisting areas, whereby to limit the adhesion of the gummed face of the tape end to those portions of said other face of said strip outside of said adhesion resisting areas.
